It is rumored that AMD Zen 3 will be used for the first time in 2020 on CPUs of the EPYC Milan. AMD released an optimized version of the Ryzen 3000XT processor series earlier this year in July, but this series will be the last to use processors (non-APU) released with the Zen 2 generation. It is planned that the Zen 3 architecture will be the first pro to debut on the EPYC server platform.
AMD Zen 3 will be first deployed on the CPUs of EPYC Milan in 2020.
Zen 3 is an improved version of the 7nm Zen 2 architecture, with the process updated from 7nm (N7) to 7nm+ (N7P). At the same time, the Zen 3 architecture continues to be updated to improve IPC performance, which should be in a reasonable range of 10-15%.
Most of the design of the Zen 2 architecture is retained, i.e. from small chips to 16 cores on the desktop, up to 64 cores on the servers, support for PCIe 4.0, and DDR4, etc., these should remain the same, and the interface will continue to be supported.
AMD has already stated several times that Zen 3 will be released in 2020, however, launching it this year doesn’t necessarily mean that it will be a desktop version.
The latest leak says that AMD’s Zen 3 will be used for the first time in the server version of the EPYC processor codenamed Milan and is expected to be officially released at the end of the year without specifying a specific month.
The desktop version of Zen 3 is not yet on the official roadmap at this time, with leaks that say the code name is Vermeer, and it could be released later this year or early next year, slightly later than the EPYC version.
The desktop version of Zen 3 was formerly called the Ryzen 4000 Series, but the series could also be renamed Ryzen 5000 to avoid confusion with the recently released Ryzen 4000/4000G.
